I did it once with a group of eight with 7 boats. We had one 13' raft and six kayaks. I can't recognize the rapid in the video, but I'm guessing it's the main falls. The thing is, you really don't have many ways out if you leave a boat. It's a pretty boxed in canyon, and I couldn't imagine hiking downstream or hiking out. It took us hours to portage Jarbidge falls, we only made about 6 or 7 river miles the day we had to portage the falls, and we had no choice but to walk everything. There wasn't enough water to get a raft down the falls like they did. Bring lots of rope should you attempt it.
